A study found an association between an increase in attendance to AA meetings with increased spirituality and a decrease in the frequency and intensity of alcohol use. The research also found that AA was effective at helping agnostics and atheists become sober. The authors concluded that though spirituality was an important mechanism of behavioral change for some alcoholics, it was not the only effective mechanism.[54] Since the mid-1970s, a number of 'agnostic' or 'no-prayer' AA groups have begun across the U.S., Canada, and other parts of the world, which hold meetings that adhere to a tradition allowing alcoholics to freely express their doubts or disbelief that spirituality will help their recovery, and these meetings forgo use of opening or closing prayers.[55][56] There are online resources listing AA meetings for atheists and agnostics.
That doesn’t seem to be the case.
